Concubine? Side Piece? What a Load of Bullshit

I grumbled and cursed at her for what felt like forever, but unlike her usual self, Lee Jieun quietly took it all in stride. Then, in a soft voice, she pleaded with me.

“Sigh… was that your goal all along? No wonder you were putting up with me insulting you like that, even though it’s so out of character for you.”

“……When you came to rescue me back then, what the hell were you thinking?”

“I’ve always been this rebellious. You’re the one who misunderstood.”

“Your life isn’t worth shit compared to mine… Sigh. What would you know? You’re just a kid.”

“Your true ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠nature is pitch-black and rotten. You just stop pretending in front of me, so it all comes out. In front of other people you’re the perfect chaebol daughter, model academy student, or vice-leader of the Revolution Circle. But in ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠front of me you’re a filthy perverted bitch who gets off on beating and raping boys and turning them into sex slaves.”

“Fuck off. Would you do it if you were me?”

“If you ever tell me to call you Master again, I’ll go straight to Big Sis Jina and spill every single thing you’ve done.”

“Before that, I’ll ask Big Sis Jina to protect me.”

…

Lee Jieun’s expression hardened as she raised an eyebrow. Her words weren’t wrong, so I got a little scared. Damn it, I can’t show weakness here… I glared at her with all my might. She stared back for a moment before averting her eyes and mumbling awkwardly.

“…Are you asking me right now?”

“Say ‘please.’”

“You want to hear the word ‘Big Sis’ so badly that you’re willing to go this far?”

“You’re a boy, so you don’t understand how magical the word ‘Big Sis’ sounds.”

Fuck. It was like watching someone back in the original world lose their mind over being called “Oppa.” Lee Jieun kept clinging to me, begging me to call her Big Sis. I eventually gave in to her whining and agreed to call her that. In exchange, she had to stop threatening me, treat me gently from now on, and delete every video and photo she had of me.

She said she understood and would do it. ‘This bitch definitely isn’t going to delete those videos…’ She claimed she was deleting them and made a ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠show of tapping on her drive, but the fact that she agreed so easily actually made me trust her less. Knowing Lee Jieun, she was probably just putting on a show while keeping backups somewhere else. But I only had suspicions, no proof, so I could only smack my lips in frustration.

Right then, Kim Jina, who had gone to the bathroom, came back out. She said she’d gone to calm her anger by herself in there. She seemed pretty pissed that Lee Jieun had taken my virgin ass. Of course, Lee Jieun didn’t know what to do with a furious Kim Jina. She even started crying, sobbing that if she’d known this would happen, she would’ve offered that cum-rag’s virgin ass to the Circle Leader instead.

Fucking bitch. The woman who took my virginity in this world keeps calling me a cum-rag. If it weren’t for you, I’d still be a pure virgin! You fucking bitch! (Probably?) Of course, because of Park Hyeji, Choi Seoa, and the Discipline Department’s gang-rape, the chances of that were slim, but thinking about historical “what-ifs” was pointless. If I hadn’t lost my virginity to Lee Jieun, maybe the butterfly effect would have kept me pure until now.

“…?”

“…Y-yeah? I haven’t.”

Is that how this works? I don’t really… get it. But I was happy. I was grinning like an idiot, so Lee Jieun secretly shot me a look of regret behind Kim Jina’s back. This bitch… She must have wanted to take my first anal experience too if Kim Jina hadn’t offered first.

Kim Jina showed incredible confidence. She did add at the end that since it was her first time too, I should forgive her if she was clumsy. Well, she said that, but since she was a pussy genius, I figured she’d be an anal genius too.

Lee Jieun headed to the bathroom. Kim Jina didn’t seem to care whether she left or not. She laid me down on the floor and got into the cowgirl position, preparing for anal. She already had her pussy dripping wet, so she used her own love juices like lotion and slathered it thickly over her asshole. On top of that, my cock, seeing her cute pink twitching asshole, got fully erect and started leaking precum in streams.

“…Y-yes.”

Her hips slowly lowered. At first they hovered around her pussy as if she were mentally preparing herself, but then she re-aimed at her asshole and came down even further. Squelch. With a lewd sound, her asshole gradually spread open around the head of my cock. The hole widened more and more. At the same time, my glans pushed deeper into her ass until it finally slid all the way in.

“Aahh…♥ It’s squeezing me differently than a pussy…♥ Ah♥ This might actually feel good…♥”

Having sex through an asshole was a completely new first-time experience for me, something I had never done in my previous life or this one. So the person who took my anal virginity—well, who let me experience it anyway—was Kim Jina, and I knew she would stay in my head for a long time.

Kim Jina, riding me in cowgirl position, clenched her asshole and began slamming down with passionate intensity. I couldn’t keep my mind straight from the strange, alien sensation and accepted the pleasure of her riding without any resistance, way too quickly.

“Heut♥ …I-I’m not curious at all…♥ Hiiik…♥ D-don’t put mana in…♥ Heuk♥♥ Ogh…♥♥♥”

Kim Jina used her cheat key. She must have poured mana into her asshole too. Did she infuse her sphincter with it? Her pink anus, already stretched wide thanks to my massive cock, suddenly clenched hard and started vibrating. Fuck, how am I supposed to hold on against this? It was like a living, warm, soft, biological vibrating onahole ass— a super anal onahole reinforced with mana.

The moment Kim Jina poured mana in for real, it felt like a flash of light went off and I lost consciousness for a second.

Spurt spurt spuuurt spluuuurt spluuuuur—!!
